SPECIZFIQATION forming part of Letters Patent No. 750,600, dated January19, 1904. Application filed November 28, 1902. Serial No. 133,039- (Nomodel.)

that class of tires known as cushion-tires c. 6., those in which anelastic body or strip is secured in a metallic rim.

The present invention designs to provide an improved tire which issimple and inexpensive of construction and which will be securely heldin true longitudinal alinement in the rim.

ith this object in View the invention consists in the several novelfeatures of construc-' tion hereinafter described, illustrated in theaccompanying drawings, and more particularly defined by claims at theconclusion hereof.

In the drawings, Figure 1 is a perspective View of a portion of a tireembodying the in- Fig. 2 is a View in horizontal section.

A denotes a metallic rim having the usual flanges, between which achannel is formed wherein an elastic body or strip B will fit and beheld.

C and C are retaining-bands in longitudi-- nal bores or openings 6,formed in and extending entirely around the elasticstrip, and thesebands secure the strip in the rim-channel.

D denotesa coil of wire embedded in the elastic strip around each of thebores b and retaining-bands D and extended longitudinally through theelastic strip. Each bore is of substantially the same diameter as theretaining wire extending therethrough, and each coil of wire has aninner diameter substantially the same as the bore, so substantially theentire inner surface of the coil will be exposed adjacent the bore. Theretainingwire will engage not only that part of the coil between theretaining-wire and rim, but also the sides and outside portions of thecoil. In

other words, the coil forms a flexible. compressible metallic liningaround the entire bore The longitudinal wire will fit snugly in the boreand spect to the rim. The coil will effectively prevent cutting or wearof the strip by the longitudinal wire, resulting from vertical andlateral pressure to which the elastic strip is subjected while in use.

In manufacturing the tires the elastic strip is sometimes molded in longstraight strips sufficient in length to encircle a rim. Cores ofsubstantially the same diameter as the retaining-wires are within themold and form the longitudinal bores, and the coils are placed aroundthese cores. The coils having substantially the same inner diameter asthe diameter of the bore and fitting snugly around the cores aretruly-alined in the elastic strip, and therefore form a truemetallic-lined bore for the retaining-wire. When the elastic strip isformed in a circular mold, the retaining-wires are endless, and theelastic strip is formed with the wire or wires therein.

An important resultant advantage is that all lateral irregularities inthe bore and strip are avoided, so the elastic strip will fit truly andaccurately in the rim-channel. advantage is that the coil or metalliclining being but little'greater diameter than. the retaining-wires willnot lessen the resiliency of the tire." I

In applying an elastic strip to the rim it is customary to compress theelastic strip so when laid into a circular rim it will possess thedesired density. the coils will permit the desired flexure andcompression and prevent the cutting either laterally or Vertically bythe retaining-wires.

Manifestly tires made as hereinbefore set forth can be economicallyproduced, are durable because cutting of the elastic body in eitherdirection is prevented by the snugly- During such operation A further acoil of Wire embedded in said strip 01' body, and extendinglongitudinally through said strip and around each of said bores oropenings, to form a compressible metallic lining for each bore, andhaving an inner diameter substantially the same as the diameter of thebore, and a retaining-Wire fitting snugly Within each bore and coil.
